Energy Audits In Bakery

With  ever increasing cost of energy  bakeries  need  to  get their plant audited once in every 3-5 year period for modification and changes in their energy management and technology  to reduce energy cost . Energy  aud
its  can be done  by  experienced  auditors  or through  institution s .

Energy Audit Methodology:

Energy Audit Study is divided into following four steps

a. Historical Data Analysis:

The historical data analysis involves establishment of energyconsumption pattern to establish base line data on
energy consumption and its variation with change in production volumes.

b. Actual measurement and data analysis:

This step involves actual site measurement and field trials using various portable measurement instruments. It
also involves input tooutput analysis to establish actual operating equipment efficiency and finding out losses in
the system.

c. Identification and evaluation of Energy Conservation Opportunities:

This step involves evaluation of energy conservation opportunities identified during the energy audit. It gives potential of energy saving and investment required to implement the proposed modifications with payback period. All recommendations for reducing losses in the system are backed with its cost benefit analysis.


d. Monitoring and Control:

With increasing energy prices, many organizations have incorporated sub-metering systems in their
plants. It is required to identify and monitor parameters for energy consumption per unit of production
or services i.e. Specific Energy Consumption (SEC).SEC monitoring is an important tool for monitoring and
proving of energy conservation measures especially to see the effect of implementation of projects directed towards energy conservation.


Major Area's  for Energy Audits

Energy Audits  has been made mandatory  by several countries . Incentives  for  better power factors  in electrical energy usage  are provided through lower bills .Few  easy  to implement plans  are suggested through these energy  audits  and the cost of  conducting such  audits  are insignificant in comparison to the savings generated   through the   suggestions and modification .
